Established in 1986, Buffalo Bayou Partnership (BBP) is the non-profit organization transforming and revitalizing Buffalo Bayou, Houston's most significant natural resource. BBP's geographic focus is the 10-square mile stretch of Buffalo Bayou from Shepherd Drive to the Port of Houston Turning Basin. Thanks to the generous support of foundations, corporations, individuals and government agencies, BBP has raised and leveraged more than $150 million for the redevelopment and stewardship of the waterfront - spearheading award-winning projects such as Sabine Promenade and Sesquicentennial Park, protecting land for future parks, constructing hike and bike trails, and operating comprehensive clean-up and maintenance programs. In 2015, BBP completed the $58 million Buffalo Bayou Park project that includes major destinations, natural landscaping, footpaths, trail lighting, water features and pedestrian bridges. Buffalo Bayou Partnership maintains and operates Buffalo Bayou Park, with annual funding provided by the Downtown Tax Increment Reinvestment Zone (TIRZ) #3. Buffalo Bayou Partnership also seeks ways to activate Buffalo Bayou through pedestrian, boating and biking amenities; volunteer activities; permanent and temporary art installations; and wide-ranging tours and events that attract thousands.
